Claims.

This invention relates to fabric roll edge protectors. I V

Fabric roll edge protectors generally consist of metal caps held. against the ends of hollow rolls 5 of fabric material by tie members extending through therolls. Such caps protect the edges of the fabrics from injury, and they also close the axial openings through the rolls sothat ma-' terials such as nails and adhesive, which are to be used with the fabrics, may be stored and shipped in the compartments ,thus formed.

Heretofore, these tie-rods have had various disadvantages, such as being relatively expensive to manufacture, difiicult or time-consuming of attachment, comprising loose parts, or requiring special tools for fastening them in place. or for removing them. With ,theseand other disadvantages. the roll protectors known previously have added unduly to the cost of fabric rolls, and

wasting. 7

It is among the objects of this in'ventionto provide a fabric roll edge protector which is simple in form, strong, inexpensive to manufacture, easy to apply and remove, and which can be quickly attached without the necessity of special tools.

The preferred embodiment of the invention is illustrated in the accompanying drawing, of which Fig. 1 is a side view of a protected fabric roll, shown partly in section; Fig. 2 an end view.

thereof; and Fig. 3 a side view of a cap-retaining member.

Referring to the drawing, a roll. 1 of material,

such as 'tar paper, building felt or other materials subject to damage at the ends, and having the customary axial opening 2 therethrough, is engaged at each end by a metal cap 3 which is in-- tended for protecting the end of the roll (edge of the fabric) from injury. These caps also cooperate with the axial opening to form a closed compartment 2a suitable for housing related materials. Each cap is preferably formed with a centrally disposed depressed or dished portion 4 extending into the axial opening of the roll. One of the purposes of this dished portion is to prevent the cap from moving laterally, that is, radially of the roll. By having the dished portions snugly engage the interior of the openings the ends of the roll are reinforced.

The caps are held against the ends of the roll by a cap-retaining member, or tie-rod, 6. In accordance with this invention, this cap-retaining member is of elongate form, preferably Wire. 5511; is provided at one end with detent means have otherwise been unsatisfactory and time,

adapted to prevent that end from passing through theapertures in the caps, e. g. a loop 'ljformed by doubling back the end' portion of the wire and twisting it upon itself. This loop is large enoughto prevent it from being drawn through '60 wire-receiving apertures 8 in) the centers'of the caps. a

In orderflto permit, the wire to' be inserted through the cap apertures, and at the same time to enable it to be quickly and easily :locked in place by a simple operation "notiinvolving :the

use of special tools theopposite end of the wire is provided with a loop 9, Fig. 3,,formed in the same way as loop 7. Prior to use this loopis narrow; that is, flattened, longitudinally of the wire so that it can be passed through apertures 81 In assembling the roll edge protectorfnarrow loop 9 is passed through aperture'8 in one of the caps, and the cap is permitted to slide along the wire until at the opposite end of the wire'it meets the wider loop '7 which engages "its outer face. This cap is then place'dflush against the end of the roll with its dished portion 4extending into the axial opening in the roll and with the wire extending through the roll. The flattened so loop, which projects fromtheoppositeend of-the 'roll, is passed through the aperture in the oth'er cap. Thiscap is then slipped along the loop until it too lies against the end of the roll with'its dished portion extending into the 'roll" openingj. The flattened loop is then expanded or spread transversely in order to bring the widened loop 9a into engagement with the outer face of the adjacent cap to prevent it from being withdrawn through the cap aperture.

In this manner the caps are locked on, or tied l1; together by, the wire, with the loops lying within the dished portions 4. 'Of course, it is apparent that the end loops are spaced no farther apart than the caps, so that the latter are not given 5 any play relative to the roll. In fact, it is preferable that the distance between the loops, before expansion of the narrow loop, be a little less than that between the caps. Then, when the narrow loop is expanded the wire is pulled taut, drawing 1 the caps tightly against the roll ends. See Fig. 3" 1. Any suitable means may be used for spreading the narrow loop, no tool made especially for thispurpose being necessary.

V In a roll edge protector constructed in accord- 5 ance with this invention, the tie rod may be made 2, from comparatively thin wire because, in spite of its thinness, it requires considerable outward pressure of the caps against the loops to flatten them out. Conseqrientlm'materials intended'for llQ use with the fabric of the roll may be safely stored and. shipped in the axial opening 2. The cost of manufacturing this cap-retaining member is small because of its simple form, and because of the light wire from which it is made. Furthermore, no difiiculty is encountered in assembling the protector, and the narrow loop may be spread quickly and easily by tools usually found at hand. f 7
